Label Checker


Summary of Label Checker GitHub check used by some RAPIDS projects.

Intended audience



Project Leads



Some RAPIDS repositories have a Label Checker check on GitHub pull requests. The Label Checker helps ensure that each pull request can be categorized correctly in our automated changelogs that get published for each release (i.e. cudf v21.06.00).

In order for the Label Checker check to pass, pull requests must include one label from each of the following categories:

  • category - categorizes the pull request
    • bug
    • doc
    • feature request
    • improvement
  • breaking - determines whether or not the pull request breaks functionality for end-users
    • breaking
    • non-breaking

Additionally, the Label Checker check will fail when the pull request includes any label which contains the string DO NOT MERGE (case insensitive).
